The code was for the manifold - when I took it in a couple of weeks ago - they took the car to service, shut it off and when they started it again it wouldn't throw the code - had the car for a week and couldn't get it to do it - gave it back to me and then on Monday the engine light came on again - drove it directly to the dealership, they wouldn't move the car or shut it off until the original mechanic could get to it - the code it was showing was the same one for the manifold. My husband went by on Wednesday and they thought it was the exhaust, so we were thinking just replace it, but when he went by yesterday that's when he was told they can't figure out where the leak is coming from so they've called in the engineer. Guess I'll find out on Monday or Tuesday.
